Just what I was thinking.Can anyone comment on whether changing/cleaning the idle control valve is a fairly simple job and also where it is located in the engine bay of a 1.8 focus?
It's normal to rev higher when cold to warm the engine, but 2000RPM does sound a little high, especially as the weather at the moment is pretty warm as it is. I think mine revs to about 1500RPM when idling from cold.
